Fitted with a sealed re-chargeable lithium back-up battery, the Ei160eRF series of mains powered radio-interlinked alarms are ideal for use where annual battery replacement and installing interlinking cables would be unsuitable. The RadioLINK module supplied with each alarm simply plugs into the back of the unit and enables up to 12 smoke and heat alarms to wirelessly interlink within a single system. All alarms are CE marked and Kitemarked to the latest standards.

The radio interlinked Ei160eRF series of alarms require a 230V AC mains power supply to each unit. Up to 12 alarms can be wirelessly interlinked by radio signal.

To obtain a mains feed, each alarm can be connected to its nearest lighting circuit using 2 core and earth cable. Please note that the separate lighting circuits must have a permanent live supply to all alarms. Radio frequency signals are then used for the wireless interlink. Please see the diagram below:-
